BACK-BAND BUCKLE.

SPECIFICATION forming part Of Letters Patent No. 622,155, dtd March 28, 1899.

Application tiled April 29, 1898. Serial No. 679,241. (No model.)

To @ZZ whom, it may concern-.-

Be it known that I, JAMES W. KIRKMAN, a citizen of the United States, residing at'Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Back-Band Buckles; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art towhich qit appertains to make and use the same.

This invention relates to back-band buckles or trace-carriers.

The object of the invention is to provide a buckle and trace-carrier readily attachable to and detachable from a back-band and which shall also have the function of retaining a trace-chain ring or link in the hook or tracechain carrier.

To this end the invention consists in the combination of a frame provided with a slot at one edge or end thereof and with a gullethook at the other end, and a band-locking link or bar coupled with the frame bymeans of the hook, the relative arrangement of slot and hook and that of the link or locking bar being such that when the bar is in operative position to lock the belt and buckle together one bar of the link will have the eiect of closing the throat or obstructing the direct passage of the hook.

What I term a gullet-hook is a hook having its point or extremity bent inward toward its shank, so that the throat between said point and 'the shank is narrower than the space between the arms or branches of the hook.

In the drawings forming a part of this specilication, Figure I is an elevation showing the buckle connected with the back-band and in operative position. Fig. 2 is a side elevation of the buckle-frame and the band-locking link detached from the back-band. Fig. 3 is a section through the back-band plate in the plane of the hook. Fig. 4 is a similar section showing a slight modification in the frame. Fig. 5 illustrates a method of loosening the back-strap to provide for dropping the link and thus permit insertion and removal of the chain ring or link 6.'

l is the frame of the buckle, struck up and formed of plate metal, having a slot 2 at one end and a gullet-hook 3 at the other end of the frame? 4 is an ordinary link, formed of heavy wire or bar metal, coupled with the frame by being inserted or formed within the hook part 3. The gage of the wire is slightly in excess of the width of the throat or passage to the hook, so that said hook is prevented from being accidentally separated from the frame. I

5 is the web or strap of the back-band, to which the buckle is locked or secured by means of the locking-link 4 in a Well-known way. The gullet-hook 3 is so arranged with relation to the slot in the frame and with the Width of the link that when one bar of the link is in operation to couple the buckle and back-band together the other bar will be within the throat and closing the throat, or so nearly closing the throat as to prevent the accidental removal of the ring or link 6 of the trace-chain from its supporting-hook, as will be clearly understood upon Aan inspection of the drawings.

In Fig. 4 I have shown the frame as being upset to form an offset 7 to provide a space into which one bar of the locking-link may be swung for the ready and convenient insertion and removal of the trace-chain link.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A combined back-band buckle and trace= carrier, consisting of the combination of a frame provided with a slot at one end, a gullet-hook at the other end, and a link one bar of which lies loosely, and is confined within, the throat of the hook, substantially as described.

2. A back-band buckle and trace-carrier involving the combination of a frame or plate provided with a slot at one end, a gullet-hook at the other end, and a link, one bar of which lies within the throat of the hook, the other bar of which is adapted to engage a backband and adj ustably secure the buckleand band together, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.

JAMES w. KIRKMAN.
